Diagnosis in Medieval Time

Main methods: analyzing the patient’s blood and urine

Blood examination

Smell Warmth Texture Taste the strength of the flow of blood

→trying to discern imbalances or impurities in the blood

Uroscopy (examining the appearance of urine) color reddish urine: internal bleeding texture watery or thick and greasy? sediment or solid in the urine gritty precipitate: kidney stone smell jordan the glass containers for the patients’ urine be

came a symbol for the medical profession

Other diagnostic technique examine a patient’s stool identify illnesses by the strength and

rapidity of the patient’s pulse astrological charts and calendars determine the nature and likely duration and

outcome of the illness based upon the date of its onset

As a result, medieval physicians had small booklets containing calendars, urine color charts and other information

The modern diagnosis about blood and urine

Equipment improvement Light microscopy Electron microscopy Immunohistological examination Cytological examination

Urinalysis

Macroscopic urinalysis-- color, texture, etc (as past)Urine chemical analysis--PH, specific gravity, protein, glucose, etc Microscopic urinalysis--RBC, WBC, bacteria, yeast, crystal, etc

Three urine samples are shown. The one at the left shows a red, cloudy appearance. The one in the

center is red but clear. The one on the right is yellow, but cloudy.

These white blood cells in urine have lobed nuclei and refractile cytoplasmic granules.

Influenza

Diagnosis

Hemaglutinin 紅血球凝集素

Sinus 鼻竇

Influenza Diagnosis

Influenza is more likely to cause fever, coughing, chills and muscle aches

More seasonal than colds, tending to occur during winter months

Blood tests Examining material from your nose

and throat

Laboratory Evaluation

Direct staining of respiratory specimens (using monoclonal antibodies (Mab) to influe

nza A and B) Isolation of the virus in cell culture with confi

rmation by Mab staining Detection by nucleic acid testing, including p

olymerase chain reaction test Demonstration of seroconversion

The Ancient Diagnostic System

Something about Qi Feeling the pulsation Observation of the complexion,smell an

d posture of the patients Ten asks

Pulse Diagnosis

Six different pulses on each wrist Three superficial and three deep
